▪ Xinglin Zeng obtained his PhD degree from Beijing University of Posts and Telecommunications in 2018. From 2016 to 2017, he went to Boston University as a visiting PhD student in the group of Prof. Siddharth Ramachandran. After PhD study, he worked as a postdoctoral fellow from 2018 to 2019 at the University of Hongkong. From 2019 to 2025, he continued to be a postdoctoral fellow and then a senior scientist in Russell division and Stiller research group in Max Planck institute for the science of light in Germany. In 2025, he joined Shanghai Institute of Optics and Fine Mechanics (SIOM), Chinese Academy of Sciences, as a full-time associate researcher and associate professor. He is also a group leader and principal investigator in RCALS.

▪ He has published more than 11 journal papers in optical journals, including Science Advances, Laser & Photonics Reviews and Photonics Research. He gave more than 20 talks in international optical conferences, including an invited talk in ECOC and 4 Post-deadline talks in CLEO-US and FiO/LS. He is the one of the chairs of Brillouin workshop at the 2025 Light Conference and a finalist for Optica Tingye Li innovation prize. He is also co-principal investigator of a German research council (DFG) project.

▪ His research interests include nonlinear fiber optics, Brillouin scattering, Chiral photonic crystal fiber, Optical vortices, and singular optics.
